Water sediments are the final repositories for natural and anthropogenic components of the ecosystem and as a result of this; there is need for constant monitoring of our environment, most importantly River sediments. This research work assesses the anthropogenic contributions of heavy metals in Elemi River sediment with the aid of statistical tools such as Enrichment factor (EF), Pollution load index (PLI) and geoaccumulation index (Igeo). The distribution patterns were in the order; Cu ˃ Zn ˃ Fe ˃ Mn ˃ Pb ˃ Cd ˃ Cr during the dry season while the wet season was in the order: Cu ˃ Zn ˃ Mn ˃ Pb ˃ Fe ˃ Cr ˃ Cd. The EF of 1.05 4.42 reflects minor enrichment to moderately enrich for all the metals except Cu (6.83) with moderately severe enrichment. The pollution load index (PLI) and index of geo-accumulation (Igeo) reflect low and uncontamination to moderately contamination of the river sediment.
